Why it works: Milk and vanilla are a kitchen classic. They rank in the top 5% of all ingredient pairs, and cooks put them together in 19,187 recipes. Both carry ethyl caproate, which smells fruity, apple peel. The science ↓
Cream Puffs
Ingredients
Directions
The book says “a moderately quick oven”. The 400°F (200°C) in the steps is the modern equivalent, not the book's own figure.
Make the choux paste
Combine ½ pint of boiling water and 2 ounces of butter in a saucepan and bring the mixture to a boil.
Add ½ pint of flour quickly. Stir rapidly until the mixture forms a ball and pulls away from the sides of the pan.
Remove the saucepan from heat. Add 1 whole egg and beat until smooth.
Add another egg and repeat until all 4 eggs are incorporated.
Drop spoonfuls of the mixture onto greased baking pans.
Bake at 400°F (200°C) for about 30 minutes.
Make the custard
Heat ½ pint of milk in a double boiler for the filling.
Beat 4 eggs, 4 tablespoons of sugar, and 1 tablespoon of cornstarch together in a bowl.
Stir the egg mixture into the boiling milk and stir constantly until the mixture thickens.
Remove from heat and add 1 teaspoon of vanilla.
Let the custard cool.
Fill and finish
Once the shells and filling are cool, open the shells on one side.
Fill the shells with the custard.
Optionally dust with powdered sugar.
Optionally coat with sweet chocolate.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Flour
- Starch that gelatinises with the eggs and water to form the puffs' structure.
- Eggs
- Provide structure and leavening through steam, and set the custard filling.
- Butter
- Adds fat and richness to the paste, softening the shells' texture.
- Cornstarch
- Thickens the custard so it holds its shape when filled.
- Milk
- Forms the liquid base of the custard filling.
- Sugar
- Sweetens the custard filling and helps it stay tender.
The step that matters
Stirring the custard constantly. Egg and starch mixtures can scorch or lump on contact with hot milk. Constant stirring keeps heat even so the cornstarch thickens smoothly without the eggs curdling.
